Test performance

Amongst all the positive noise about virtualization, I noticed what appeared to be a negative article here. It advised that you approach virtualization with caution. The underlying concern was that performance was not considered appropriately. And what did it recommend to address this? Why, performance testing of course.

"Performance Testing and resource consumption needs to be conducted on a few servers or workstations with a proper backup for redundancy and failure. Setup tools need to be built in order to monitor and correct performance issues."

The article goes on to fragmentation issues in the virtual environment and bottlenecks. The latter is of course another reason for performance testing. So on closer inspection, it is not so much an anti virtualization article but rather a pro performance testing article. Positive after all.
